The reactions between the pentafluorophenylphosphines PPhx(C6F5)3-x (x = 0-2) and the dimeric platinum(II) species 2> yielded the complexes trans-x(C6F5)3-x>> (x = 0 1, 1 2, 2 3).The molecular structure of complex 3 has been determined by single-crystal X-ray crystallography, it crystallizes in the triclinic space group with z = 4 with two independent molecules in the asymmetric unit, a = 12.067(2), b = 14.131(1), c = 16.393(2) Amngstroem, α = 76.92(1), β = 79.08(1), γ = 89.40(1) deg.Varable-temperature 19F NMR spectroscopic studies, performed at 282.41 Hz, were carried out and showed that there is hindered rotation about the P-C6F5 bonds of complex 1, which was frozen out at 197 K.There was no evidence of hindered rotation about the P-C bonds of complexes 2 and 3 down to 184 K.
